Abstract

Certain sugar derivatives have bleach-activating effect both on ''hydrophilic'' stains (e.g. tea or red wine) and on ''hydrophobic'' stains (e.g. grass or tomato sauce). The compounds in question are derivatives of pentoses or hexoses, having a long-chain acyl group and one or more short-chain acyl or aroyl groups attached through ester bonds. Optionally, a short-chain alkyl group is attached through a glycosidic bond. These compounds are non-toxic and biodegradable, and can conveniently be prepared by methods known in the art.

~ACKGP~Gu~iD i~sT

It is well known that detergents comprising peroxygen bleaches such as sodium perborate (PB) or sodium percarbonate (PC) are effective in removing 10 stains from textiles. It is also known that the bleaching effect at temperatures below 50 C can be increased by using a peracid precursor (bleach activator) such as tetraacetylethylenediamine (TAED), nonanoyloxybenzenesulfonate (NOBS, described in US 4,412,934), 3,5,5-trimethylhexanoyloxybenzenesulfonate (ISONOBS, describedin EP 120,591), or pentaacetylglucose (PAG), which is perhydrolyzed to form a 15 peracid as the active bleaching species, leading to improved bleaching effect.
EP 325,100 proposes use of an acetylated sugar ether containing a long-chain alkyl group as a bleach activator. However, such compounds cannot be easily prepared.
It is the object of the invention to provide use of an improved bleach 20 activator.

DETAILED DESCRlPTlON OF lHE INyFNTION

Hvdroaen peroxide source The invention uses a hydrogen peroxide source as a bleaching agent, 20 i.e. a compound that provides hydrogen peroxide in an aqueous detergent solution. Examples are hydrogen peroxide itself, perborates such as sodium perborates and percarbonates such as sodium percarbonate.

Wo 91/107l9 PCrtDK91/00016 2 ~ 7 8 4 Suaar derivative The sugar derivatives according to the invention consist of a pentose or hexose sugar moie~, substituted with a long-chain acyl group and one or more short-chain acyl or aroyl groups through ester bonds, and optionally substitutedith a shor~-chain al'<yl sroup through a glycosidic bond.

The long-chain fatty acyl group may be saturated, mono- or poly-unsaturated; straight-chain or branched-chain, preferably C8-C18. Some preferredacyl groups are octanoyl, nonanoyl, decanoyl, undecanoyl, dodecanoyl, tetra-decanoyl, hexadecanoyl, octadecanoyl, 1 ~undecenoyl, oleoyl, 2-ethyl-hexanoyl and 3,5,~-trimethyl-hexanoyl. C8-C12 hydrocarbyl groups are particularly preferred as 20 they provide good bleach activation on hydrophobic stains.
The short-chain acyl or aroyl group is preferably a C2-C6 acyl group (especially acetyl) or benzoyl. Such derivatives can be prepared conveniently and economically.
The sugar moiety may be an aldohexose or aldopentose. For reasons 25 of economy, glucose or xylose derivatives are preferred.
Alternatively, the sugar moiety may be a ketohexose or ketopentose.
For reasons of economy, fructose derivatives are preferred.
In the case of glycoside esters (y=1), those with methyl or ethyl as the alkyl group R" may be preferrsd as they provide good surfactant properties.
30 The glycoside bond may be in the ~- or 13-anomeric form.

Amcng the sugar esters (y=0), compounds having one of the acyl-groups attached to the anomeric C-atom (the 1-position of an aldose or the 2-position cf e '~^se) ~rQ crsferred as they ars most rapidly psrhydrolyzQd.

rhe sugar derivatives may be in the pyranose or furanose form 't .ol,û~,v, from the above that the number n y + 1 of acyl and alkyl substituents in ~he sugar molecule may vary from 2 up to 4 for a pentose or up to 5 for a hexose. Derivatives with only 2 or 3 substituents (n+y = 1 or 2) may be preferred as they are more hydrophilic than those more fully substituted and 15 are therefore more easily dissolved and may furthermore be more efficient as surfactants.
Alternatively, it may be preferred to use fully substituted compounds (n+y = 3 for a pentose or 4 for a hexose), as these provide the maximum amount of peracid.
Sugar derivatives with the long-chain acyl group attached to a side chain of the sugar molecule (i.e. to the ~position of glucose or the 1- or 6-position of fructose) may be preferred when a relatively slow release of the long-chain peracid is desired, so as to retain a surfactant effect, while short-chainperacid still may be formed rapidly by perhydrolysis in other positions of the 2~ molecule.
I o ensure good stability, the bleaching detergent composition of the invention will generally be provided in particulate form. Preferably, the sugar darivative cf fcr",ula (I) should be present in crystalline form, and for good crystallization it is preferable to use the sugar derivative in pure form rather than 2 ~ 7 8 6 a mixture of isomers.

Many of the sugar derivatives used in the invention are effective as 15 non-ionic surfactants. In addition, the composition of the invention may comprise other surfactants, e.g. of the non-ionic and/or anionic type. Examples of nonionics are alcohol ethoxylates (AE), nonylphenol ethoxylatss, alkyl polyglycosides (APG), and monoesters of carbohydrates (e.g. of free sugars or of glycosides). Examplesof anionics are linear alkylbenzene sulfonates (LAS), fatty alcohol sulfates, fatty 20 alcohol ether sulfates (AES), ~-olefin sulfor,atrs (AOS) and soaps.
Further, the composition of the invention may contain other conventional detergent ingredients such as suds-controlling agents, foaming boosters, chelating agents, ion exchangers, alkalis, builders, cobui!ders, otherbleaching agents, bleach stabilizers, fabric softeners, anti-redeposition agents, 25 enzymes, optical brightaners, anti-corrosicr, as_nts, f, a5l ar,cas, dya-stu,fs, blueing agents, formulation aids, fillers and water The composition of the in~/en~Jr may be prs~/idDd in liquid form 5r in powder or granular form, It may be isrrr_iatecl in anaiogy with the frama formulations for powder detergents given at p. 288 of J.

EXAMPLES

The preparations of the susar d-r,vatives w6re gPnerally mixtures of the ~- and ,B-anomers. In all cases satisfactory ' H-NMR spectra were obtained for WO 91/10719 PCr/DK91/00016 2 ~ 7 ~ 8 the preparations. The preparations were all approximately 90% pure, but were dosed in the bleaching experiments as if 100% pure.

It has been checked that me~hanol/-ethanol at .~ ls attained by adding the sugar derivatives in this way have no influence in -he e~parimenis performed.

ECAMPI~ 1 This example is concerned with an examination of glucose ester and 10 glycoside ester preparations as activators for hydrogen peroxide in the bleachirig of test swatches soiled with tea, red wine, or grass.
The test swatches used were prepared by homogeneousiy soiling cotton cloth with tea, red wine, or grass juice, and then air-drying the soiled cioth overnight in the dark. The resulting material was stored in the dark at 4C (tea, red 15 wine) or below 0C (grass) for at least 2 weeks before cutting test swatches.The experiments were carried out as small-scale analogues of a Terg-o-tometer washing trial, i.e. isothermally in a series of beakers with concertedstirring (and alternating stirring direction). The soiled textile was loaded to 9 g/l washing liquor.
The washing liquor employed was a 50 mM sodium carbonate buffer at pH 10.5 with 0.4 g nonionic surfactanVI added (the preparation Berol 160 fromBerol Nobel was used, a C12-C14 fatty alcohol ethoxylate with an EO value of 6).The washir;g liquor was prepared from demineralized water.
Washing temperature was 40~C.
Duration: 30 min After washing, the swatches were rinsed thoroughly in tap water and then air-dried in the dark overnight.

10 acylated compound 1 ,2,3,4-tetra-O-acetyl-6-O-octanoylglucose (TAG-6-8, for short) was monitored by the amount of peracid formed in a model washing liquor (peracid formation may be monitored for example by iodometry at 5 C as described by Sully and Williams in Analvst, 1962, 67, 653).
The experimental conditions were: 10 mM H2O2 in 50 mM sodium 15 carbonate buffer (prepared from demineralized water) at pH 10.5 with 0.4 g nonionic surfac anVI added (the preparation Berol 160 from Berol Nobel was used,a C12-C14 fatty alcohol ethoxylate with an EO value of 6). TAG-6-8 was dosed to a level of 2 mM. The results are shown in Table 3:
T2ble 3 Time ~min) ¦ ~eracid ~m~) 3 1 3.0 2 . 7 __ The above data show that TAG-6-8 should be a very efficient activator for peroxide compounds since 3 mM peracid is formed in only 3 minutes from a 30 2 mM solution OT TAG-o-8.

O compound~ "_. 3 b_have more or less identically on red-wine and tea stains, while the C10 compcund is clearly superior on grass.
For the compounds TAG-1-10 = 2,3,4,6-tetra-0-acetyl-1-0-decanoyl-glucose (as a preparation with more than 95% ~-anomer) and TAG-1-(10-undecenoyl)=2,3,4,0-tetra-O-acetyl-1-0-(1~undecenoyl)glucose (~:~ ratio approx 15 7:3) dose-effect studies analogous to the above ones are presented in Figures 3 and 5. It is seen that with the long-chain acyl placed at the anomeric carbon, an even better effect is obtained on the hydrophobic stain, i.e., grass, in comparison with the TAG-8 compounds, while maintaining significant effects on the hydrophilic stains. The two TAG-1 compounds behave very similarly.
Finally, in Figure 4 a comparison is made between the bleaching behavior on grass soiling of three of the TAG-fatty acyl compounds and the reference activator PAG (pentaacetylglucose), the most closely related compound within the prior art. it is seen that on this soiling, a signKicant improvement results from the substitution of one acetyl group by a long-chain acyl group, whether in2~ the 1- or the ô-position.

The test employed Miele (Model W756) Washing Machines employing 105 9 of a detergent product in a 60C mainwash cycle with 1 1 litres of water (city water of a hardness of approx. 12- dH). Each machine was loaded with 18.1 kg of normally soiled domestic fabrics (shirts, tea towels (dish towels), sheets, bath towels) together with swatches of technical stains representing greasy stains, 15 hydrophilic (bleachable) stains and hydrophobic stains. The greasy stains were lipstick, maka-up, boot-polish, eye-shadow, and dirty motor oil, all painted onto cotton and aged for two months. The hydrophilic (bleachable) stains were tea, wine, and coffee, all boiled onto cotton, and curry and blackberry, painted on and similarly aged. The hydrophobic stains, painted on and aged similarly, were ragu20 sauce, tomato paste and siciliana sauce. In addition a number of naturally soiled articles were split ito two halves,one of which was washed using the TAED-containing product while the other was washed in a product containing either PAGor TAG-1-10.
The detergent product had the following composition in weight 2~ percent.
